Mez - I'm glad your getting it checked out. I had to wear a monitor for a month several years ago because I was getting palpitations.
Same thing, where I had to call in the signals using a phone. What a PITA.
This was after I had lost about 25 pounds.
After all that, the doc said that the palpitations were a normal thing to happen as you age and also that my weight loss and change of metabolism could have been causing them.
I rarely get them anymore.
So - my thoughts are with you.
